sea urchins
Will sea urchins eat or damage any soft corals?

i don't think they will eat them (??) but they tend to bulldoze over everything, and whatever they knock over almost always ends up jelly side down in the sand

I ended up moving things out of its reach... with out strong effort..
He seems to have cooled down.. but when I first got him he was out to make a statement.

Some won't. Diadema, or Black long-spined urchins are good, as I understand. I've got one in my tank. "Carrier Urchins", (Arabica punctulata?) might be good, but I couldn't tolerate their clumsiness. They pick up things and carry them around, and bulldoze fairly substantial liverock. Things being mostly coral frags in my case, so I traded him in. Amazing how neat and orderly the frag tank became after he was gone! |

I had a black spiny urchin (?). He was awsome at eating algae but he also ate corraline algae. Which makes since because it encourages hair algae to grow which ensures them a food source. I couldn't sleep well after hearing so many horror stories so i took him back. I would advise against it unless you can find a perfect species(which is possible) or have a huge algae problem.

my long spiny urchin was an algae eating machine. unfortunately, he was also a pooping machine. i took him back to lfs and the tank has never been cleaner.

I love mine although he did gobble up some Xenia I bought about a month ago. Otherwise, yes they do eat coraline..thats ok that just promotes coraline growth. Yes, they do poop alot but that goes with the teritory. So far mine has only "bulldozed" 1 frag in the yr and a half I've had him.

Well Urchins are nice I guess.. But the tuxedo was my last.. I have him in the tank still but I keep an eye on him and move him when gets to close to things...
Yesterday the little dirty rat rolled right over a patch of mushrooms I had .... they made it except one that is now on the urchins back.... heh
